Fig. 5.

Graphic illustration of the percentage changes from baseline for each parameter measured in the control flap group compared with the selective venous occlusion flap group (note the scale differences on the y axis). Baseline measurements are from −10 minutes to 0 minutes. Selective venous occlusion occurred at 0 minutes. The p values reflect the differences over the entire time course between the curve representing the control flap group (gray) and the selective venous occlusion flap group (color). A Bonferroni posttest analysis found a statistically significant difference (p < 0.05) in percentage change in oxyhemoglobin at 8 minutes, percentage change in deoxy hemoglobin at 2 minutes, percentage change in total hemoglobin at 4 minutes, and percentage change in tissue saturation at 1 minute following selective venous ligation.
